Samaylenko, V.S. 1970. The effect of wind and solar 

 radiation upon the ocean. (Nature of the Peru 

 Current). Oceanology 10(1):1-12. 



A description is given of the major oceano- 

 graphic and meteorological features off Chile 

 and the Peru Current areas. He noted the 

 stability of oceanic and atmospheric condi- 

 tions and the long-term sameness of the re- 

 gion. He concluded that the role of insola- 

 tion is insignificant on water temperature 

 due to the persistant cloud cover. He showed 

 a cool surface water layer not being due to 

 advection but to vertical advection/upwell ing 

 of deep water to the surface. The main rea- 

 son for a cool Peru Current is the divergence 



responding to the southeast tradewinds. 



KEY WORDS: oceanography, currents, tempera- 

 ture, meteorology, winds.

 in relation to the general oceanographic condi- 

 tions off Chile and Peru. Bull. Far Seas Fish. 

 Res. Lab. 5:23-88. 



A general descriptive review of southeastern 

 Pacific oceanography, currents, etc. Shows 

 the distribution of numerous properties along 

 the South American coast, all in relation to 

 the abundance of yellowfin, albacore, bigeye, 

 and marlin. 



KEY WORDS: tuna, albacore, bigeye, yellow- 

 fin, catch, distribution, season, migration, 

 oceanography, upwelling, fronts, water mass, 

 temperature, salinity.

 graphic conditions in the Northeastern sea area.

 p. 1-21 [Transl. from Japanese by W.G. Van 

 Campen . ] 



A tabulation of the temperature range of tuna 

 catches by month in the local Japanese fish- 

 ery. The main fishing grounds were within 



the favorable water temperatures of 20 to 



o 

 24 C at the surface and especially at marked 



current boundaries where the isotherms clump. 



KEY WORDS: tuna, skipjack, oceanography, 

 temperature, currents, isotherms, boundaries.
